BACKGROUND: Stent graft-induced new entry has been described in thoracic endovascular aortic repair for aortic dissection. The incidence of stent graft-induced aortic wall injury (SAWI) related to iatrogenic injury in nondissections is incompletely described. We describe incidence, risk factors, and outcomes of SAWI.
METHODS: All post-thoracic endovascular aortic repair computed tomography angiograms (January 2005 to December 2018) were reviewed for radiographic evidence of SAWI. Endograft-induced aortic dissections were likewise considered SAWI. Patient characteristics, time to SAWI, and need for reintervention were noted. Cox proportional hazards modeling was used to identify risk factors for SAWI.
RESULTS: Within the study cohort (n = 430), 38 patients (9%) had SAWI during a median follow-up of 2.3 years (interquartile range, 4.8); 42% (n = 16) were proximal, 53% (n = 20) distal, and 5% (n = 2) both proximal and distal. Nine (23%) were distal intimal flap injuries in dissection cases, thus subclassifying them as stent graft-induced new entry. Twenty-nine percent of SAWI (n = 11) required reintervention. Of these, 45% (n = 5) were open, and 55% (n = 6) were endovascular. Thoracic endovascular aortic repair for acute dissection had a higher incidence of SAWI development (hazard ratio 4.6; 95% confidence interval, 2.4 to 9; P < .001) as compared with other indications. Use of devices with proximal bare springs or barbs was also associated with increased SAWI incidence (hazard ratio 5.3; 95% confidence interval, 2.6 to 11.0; P < .001).
CONCLUSIONS: The rate of SAWI after thoracic endovascular aortic repair is low (9%), but nearly one third will require reintervention. Thoracic endovascular aortic repair in the setting of acute dissection and use of devices with proximal bare springs or barbs were associated with an increased incidence of SAWI.
